In 1972, Maschler, Peleg and Shapley proved that in the class of convex the nucleolus and the kernel coincide. The only aim of this note is to provide a shorter, alternative proof of this result.

In February 2006, an Alternative Platform Observer Program (APP) was implemented in North Carolina (NC) to observe commercial gillnet trips by small vessels [<24 ft (7.2 m)] in nearshore waters out to three nm (5.6 km). Efforts began with outreach to the fishing industry while simultaneously gathering information to be incorporated in a Database of Fishermen. From 30 March 2006 through 31 March 2007, 36 trips were observed. Observed trips of the NC nearshore gillnet fishery targeted seven species: kingfish (Menticirrhus spp.), Spanish mackerel (Scomberomorus maculatus), spiny dogfish (Squalus acanthias), spot (Leiostomus xanthurus), spotted seatrout (Cynoscion nebulosus), striped bass (Morone saxatilis), and weakfish (Cynoscion regalis). Of the 36 trips, 20 (55.6%) were with vessels that were new to the Northeast Fisheries Observer Program (NEFOP), having never carried an observer. Based on the landings data for small vessels from North Carolina Division of Marine Fisheries (NCDMF), the APP has achieved 10.1% coverage by number of trips and 4.0% by pounds landed. No incidental takes of bottlenose dolphins were observed by the APP, although bottlenose dolphins were sighted during 19 (52.8%) observed trips. The APP has drastically increased the number of observed trips of small vessels in the nearshore waters of NC. When combined with trips observed by NEFOP (n=205), the APP resulted in a 15.6% increase in the number of observed gillnet trips. (PDF contains 34 pages)

Digital text benefits a wide range of learners, particularly disabled learners. For those with a visual impairment, it can be magnified or read out loud using synthetic speech. It can be navigated by heading and subheading levels, and text colours and backgrounds can be altered, both useful features for dyslexic learners. Definitions of unfamiliar words can be checked without leaving the text.

This series of five documents is a result of research carried out with a grant from CLAUD (a group of HE librarians in South West England who are working to help create libraries accessible to users with a disability). The research involved over 60 responses representing 49 different Higher Education Institutes (HEIs).

For many learners, course materials in standard print format are difficult to use. Getting these in alternative formats could make a big difference but how do you find out what the options are? This guide seeks to provide an overview of the alternative formats available and how you can create them.

The cod stock in the Western Baltic Sea is assessed to be overfished regarding the definitions of the UN World Summit on Sustainable Development at Johannesburg in 2002. Thus, the European Fisheries Council enforced a multi-annual management plan in 2007. Our medium term simulations over the future 10 years assume similar stock productivity as compared with the past four decades and indicate that the goals of the management plan can be achieved through TAC and consistent effort regulations. Taking account of the uncertainty in the recruitment patterns, the target average fishing mortality of age groups 3 – 6 years of F = 0.6 per year as defined in the management plan is indicated to exceed sustainable levels consistent with high long term yields and low risk of depletion. The stipulated constraint of the annual TAC variations of ±15% will dominate future fisheries management and implies a high recovery potential of the stock through continued reductions in fishing mortality. The scientific assessment of sustainable levels of exploitation and consideration in the plan is strongly advised, taking account of uncertainties attributed to environmental and biological effects. We recommend our study to be complemented with economic impact assessments including effects on by-catch species, which have been disregarded in this study. It is further demonstrated, that the goals of the management plan can alternatively be achieved by mesh size adaptations. An alternative technical option of mesh size increases to realize the required reductions in fishing mortality provides avoidance of discards of undersized fish after a few years by means of improved selectivity, another important element of the Common Fisheries Policy. However, it is emphasized that technical regulations since 1990 failed to affect the by-catch and discards of juvenile cod. In any way, the meaningful implementation of the multiannual management plan through stringent control and enforcement appears critical.

Fischfanggeräte werden in der kommerziellen Fischerei und in der Fischereiforschung eingesetzt. In beiden Fällen werden hauptsächlich Schleppnetze verwendet. Schleppnetze sind jedoch nicht für alle Aufgabenstellungen der Fischereiforschung geeignet. Alternative in der Forschung verwendbare Untersuchungsgeräte und Methoden wurden bisher ohne überzeugenden Erfolg getestet. Schleppnetzen – insbesondere den Grundschleppnetzen der Berufsfischerei – werden sowohl die Meeresumwelt schädigende Einflüsse als auch unzureichende selektive Eigenschaften hinsichtlich Ziel- und Beifangarten nachgesagt. Die in der kommerziellen Fischerei der Ostsee verwendeten Schleppnetze üben aber nur einen geringen schädlichen Einfluss auf Bodenorganismen aus. Alternative ökosystemgerechte Fanggeräte wie Fischfallen können Schleppnetze bisher nicht ersetzen. Es werden Möglichkeiten aufgezeigt, die negativen Einflüsse auf die Meeresumwelt noch weiter zu verringern. Durch konstruktive Gestaltung der Schleppnetze (großmaschige Unterblätter im Vornetz, im Oberblatt reduzierte Grundschleppnetze) können Beifänge reduziert werden. Durch weitere Verbesserungen der Beschwerungs- und Spreizelemente an Grundschleppnetzen lassen sich die negativen Einflüsse auf den Meeresboden weiter reduzieren.

A study was embarked upon with the twin objectives of reviewing the Green Revolution Strategy for accelerating fish production in the country and proposing an alternative strategy, a private sector approach. Some of the programmes listed in the Green Revolution are very necessary for developing a viable - fish farming industry and that money spent under such programmes is money well spent. Programmes that are also desirable but need to be considerably expanded were identified. Other programmes have been criticised on the grounds that the method chosen to achieve the desired objectives is fraught with dangers if sufficiently long run view of fisheries development is taken

Details are given of a study conducted in the framework of the Kainji Lake Fisheries Promotion Project to boost income from alternative sources. The project identified 'improved poultry keeping' as suitable for introduction around the Kainji Lake area. In the long term, the programme will assist increasing especially the income of female members of fishing families, since poultry is kept in the villages mainly by women. (PDF contains 35 pages)
